AI Article Synopsis
- The study used infrared spectroscopy and mass spectrometry to analyze chemical reactions in water-oxygen ice mixtures under extreme conditions.
- Researchers confirmed the formation of various molecules like hydrogen, isotopically substituted oxygen, ozone, hydrogen peroxide, hydrotrioxy, and dihydrogentrioxide as products of the reactions.
- The findings help propose kinetic models and mechanisms for these reactions occurring in icy environments found in the solar system.
Article Abstract
In order to investigate the chemical reactions inside water-oxygen ice mixtures in extreme environments, and to confirm the proposed reaction mechanisms in pure water ice, we conducted a detailed infrared spectroscopy and mass spectrometry study on the electron irradiation of H(2)(18)O/O(2) ice mixtures. The formation of molecular hydrogen, isotopically substituted oxygen molecules (18)O(18)O and (16)O(18)O, ozone ((16)O(16)O(16)O, (16)O(16)O(18)O, and (16)O(18)O(16)O), hydrogen peroxide (H(18)O(18)OH, H(16)O(16)OH and H(16)O(18)OH), hydrotrioxy (HOOO), and dihydrogentrioxide (HOOOH) were detected. Kinetic models and reaction mechanisms are proposed to form these molecules in water and oxygen-rich solar system ices.
